What is the boron carbide property?
Boron carbide powder Also known as black Diamond, this organic substance is a powder with the chemical formula B4C. It’s usually a gray or black color. It is among the three hardest substances known (the two others being diamond and cubic boron-nitride).Boron carbide looks like a shiny black crystal. Boron carbide has a harder surface than industrial diamonds, but is softer than silicon carbide. Compared to other ceramics, boron-carbide ceramics are less fragile.
Boron carbide powder has a high stability to acids and alkali solutions. Boron carbide in air is essentially stable below 800degC. The boron oxide that is formed when it is oxidized at higher temperatures, is lost in gas phase. This leads to its instability.
What are the uses of boron carbide?
Boron carbide is a powder with low density and high strength. It also has good chemical stability, a high temperature stability, and possesses favourable thermal stability. It’s used as a ceramic reinforcing phase, in materials that are resistant to wear, and in armor, neutron absorbers for reactors, etc. As boron carbide can be easily manufactured and has a low cost, it is used more than diamonds and cubic boron. It can be used to replace expensive diamonds at certain locations and is often used for grinding, drilling, and grinding.Abrasive material
The boron-carbide has long been used in the manufacture of coarse abrasives. Due to its high melting point it is difficult for it to be cast in artificial products. However it can be shaped by melting the powder at a high temperature. Boron carbide powder can be used to polish, grind, drill, and grind hard materials, such as gemstones and cemented carbide.
Coating paint
Boron carbide may also be used on warships or helicopters as a ceramic surface. It is lightweight with the ability to resist armor-piercing bullets.
Nozzle
Due to their high hardness and resistance to wear, boron-carbide nozzles will eventually replace materials like cemented carbide/tungsten and silicon carbide.
Other
Boron carbide powder can also be used for the production of metal borides as well as boron alloys and welding.
